Pedrollo FYG-32 is a high-pressure mechanical pressure switch designed for automatic control of pump equipment in water supply systems. The model features an extended pressure adjustment range — up to 10.5 bar, making it ideal for systems with high pressure requirements and stable operation needs.

Operating Principle

The Pedrollo FYG-32 switch automates pump operation as follows:

▪️When pressure in the system drops below the set lower limit, the pump switches on automatically.
▪️When the upper pressure threshold is reached, the pump shuts off, preventing overload and overfilling.

The device monitors changes in pipeline pressure and closes/opens the power circuit, ensuring precise control of water supply without manual intervention.

Technical Specifications:

▪️Model FYG-32:
 - Pressure range: 5.6 – 10.5 bar
 - Factory setting: 8.0 – 10.5 bar
▪️Minimum delta (difference between ON and OFF): ≥ 1 bar
▪️Operating voltage: 220 V
▪️Maximum current: 10 A
▪️Connection type: 1/4" female thread
▪️Maximum installation height: up to 3 m below the highest water intake point

Features and Benefits:

▪️ Extended pressure range — ideal for high-pressure systems
▪️ Easy installation on pipeline
▪️ Reliable pump control without additional electronics
▪️ Compatible with surface and submersible pumps, and pump stations
▪️ No complex configuration required — parameters can be adjusted manually with tuning screws

Application Areas:

▪️Water supply for private houses, cottages, farms
▪️High-pressure irrigation systems
▪️Commercial and industrial water networks
▪️Pump stations in residential and office buildings
▪️Systems with high water lift requirements

Model FYG-32 does not include dry-run protection, so it is recommended for use only with a pressure tank (hydroaccumulator) and when water is present in the system. If the pump may operate dry, a separate protection system must be installed.

Pedrollo FYG-32 is a reliable solution for stable and powerful pump operation under heavy loads. Its simple design, wide pressure range, and compatibility with various types of pumps make this switch an essential component in automatic water supply systems.
